THREAD-GUARD FOR CAP SPINNING AND TWISTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 359,007, dated March8,1887.

(No model.)

To (ZZZ whom it may concern.-

Be it known that LLEEDHAM BINNS,0f Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented new and usefulImprovements in Thread-Guards for Cap Spinning and Twisting Machines, ofwhich the following is a full, clear, and exact description.

This invention relates to the guards used in cap spinning and twistingframes to prevent the several yarns from interfering or entangling witheach other when being spun and twisted.

The invention consists in a novel construc tion of the guards, of partlycircular form at their backs and of a peculiar shape at their frontedges; also, in a combination of the guards, made to interlock with oneanother at their front edges, and the back board, top board, and capsand spindles of the frame ormachine,substantiallyashereinafterdescribed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 represents a mainly sectional side view only of so much of acap spinning and twisting frame as is necessary to illustrate myinvention, the same showing but asingle spindle and cap with partsimmediately pertaining thereto and with my improved guard applied. Fig.,2 is a partially-sectional plan view showing the back board of themachine and a pair of my improved guards applied to a couple of caps andtheir spindles. Fig. 3 is a front elevation of one of the guardsdetached.

A indicates the back board of a cap spinning and twisting frame ormachine, and B the usual top board thereof.

O is one of the top rollers, and D one of the bottom rollers, betweenwhich and down through an eye in the top board each yarn 1) passes toits respective spindle c, or bobbin d thereon.

E is the spindle-cap; e the whirl by which the whirl-tube 0 is rotatedupon the fixed spindle c. f is the traversingrail, and g the foot orspindle rail, all as in other cap spinning and twisting frames.

G G are the guards between the caps E. These guards run up to the underside of the top board, B, and extend to the bottom of or a little belowthe caps, or thereabout, as usual. Said guards, which may be made out ofsheet metal, are bent or shaped so that they assume in horizontal ortransverse section a partlycircular form, corresponding to orapproximating a half-circle, concave on their inside at their backs h,-and in some cases I make their tops of a partial bell or dome shape,thereby entirely dispensing with all angular nooks and corners, andallowing the yarn to travel perfectly at ease and so that as it isrotated it will only once at each revolution strike the guard or guardson what may be called the going-on side-that is, on the left or righthand side, accordingly as the yarn is being spun or being twisted ordoubledinstead of striking on the sides of adjacent guards and innersurface of the back board. This reduction in the striking of the yarnenables the latter to be twisted more perfectly and steadier,

and the yarn coming in contact with the interior curved surface of theguard has its outside fibers rolled onto it instead of being battered,thereby causing less waste and making a smoother or polished yarn. Noawkward corners or angular spaces are left within the guards or betweenthem and the back board or top board for the collection of hairs, fuzz,or waste; but the guards maybe quickly wiped out by rubbing a cloth upand down within them, if necessary, at distant periods of time, toremove any such material as may be left there, instead of having tofrequently pick it out of angular spaces between the guards, back board,and top board. This will greatly economize labor and there will be lesswaste.

The guards G may be fastened to the back board,A,by a single row ofscrews, .9, arranged centrally down the back of them. Their forwardvertical edges, which stand out in front 011 opposite sides of the cap,are constructed so that the one edge, It, is plain and straight, whilethe other edge, Z, is turned over to form a lap or pocket for the plainstraight edge 70 of the next guard to engage and iit within, after thefashion of a tongue-and-groove joint. This construction provides for theseveral guards throughout the whole row of spindles, or for any numberof them, supporting one another in front, thus making them solid orsubstantial in front as well as at their backs, instead of, as in thecase of the ordinary double guards,

depending upon wings to hold them at their backs and leaving them looseor free in front, and consequently liable to get out of position.

2. The combination, in a cap spinning and twisting frame, of a series ofguards, G, having curved backs continuous with their sides and Havingthus described my invent-ion, what I made t-ointerlock with one anotherby tongueelaim as new, and desire to secure by Letters and-groove jointdown their front edges, the

Patent, is

1. The within-described guard for cap spinback board, A, to which saidguards are secured in their rear, the top board, 13, the caps nin andtwistin frames of part] circular E and s indles c essentially asdescribed.

#3 b 1 i y 2 V i construction at its back h,and having a straight frontedge, is, on one side and a turned-over front edge, Z, on its oppositeside, substantially as specified.
